Hinge



Patented dem. 14, 1930 JOSEPH BOSS, F BROOKLYN, NEW YORK HINGE Application led September 21, 1927. Serial No. 220,924.

This'invention relates to hinges and par- Fig. 7 is a section on the line 7-7 of Aticularly to devices of this class, the separate butts of which are composed of sheet metal and fashioned to form a plurality of pintle bearings extending longitudinally of the hinge to provide an elongated hinge structure for supporting a door or other swinging member` in connection with a stationary support or door frame; and the object of the invention is to provide a hingeof the class specified, one of the butts of which is fashioned from a single sheet of comparatively thin sheet metal, in such manner as to provide a plurality of cylindrical pintle bearl5 ings, spaced longitudinally of one side edge of the butt and contained within a hood portion forming what is known as a covered joint hinge wherein a plurality of cylindrical pintle bearings or knuckles are arranged longitudinally of the hood portion and recesses intermediate said bearings for receiving the pintle bearings or knuckles of the other butt of the hinge; a further ob'ect being to provide a hin e butt of the c ass described which is so ashioned as to produce, longitudinally of the free edge of the hood portion, a stop shoulder for limiting the movement of the separate butts one upon the other; and with these and other obects o in view, the invention consists in a hinge of the class` and for the purpose specified, which is simple in construction, eiiicient in use, and which is constructed as hereinafter Vdescribed and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are desigeach of the views, and in which Fig. l is a side view of a hinge made according to my invention, with part of the construction broken away and in section.

Figs. 2 to 5 inclusive are sectional vi'ews, showing the successivesteps in the formation of one the butts of my improved hinge.

Fig. 6 is a section on the line 6-6 of Fig. 1.

nated by suitable reference characters in Fi l; and,

ig. 8 is a sectional view, showing a modification.,

In the drawing, 10 represents one of the butts of the hinge, and 11 the other butt' thereof. The butt 10, in the construction shown, is formed from a sin le sheet of metal, the central portion of w ich is fashioned to form a plurality of cylindrical'bearings 10, spaced longitudinally thereof and between which are recesses 10h to receive the pintle bearings or knuckles of the .butt 1l.

The butt 11 is fashioned from a single sheet of metal, the central ortion of which is cut out to form a plur ity of apertures l2, spaced longitudinally of the sheet and between which are web portions 13, one web portion and one aperture being represented in Fig. 2 of the drawing. The web portions 13 are then fashioned to form substantially cylindrical members 14 as indicated in Fig. 3 of the drawing, by bringing the side parts 11 and 11b of the sheet together to form the `shank of the butt, after which the members 14 and adjacent part of the shank are curled upon the shank of the butt as partially indicated in Fig. 4 until the parts assume the position shown in Fig. 5, in which position it will be noted that the bearings 14 which constitute the pintle bearin sof the butt are contained within a hoo portion 15 of a double wall thickness where the bearing members 14 are located, and of a single wall thicknessintermediate said bearings at the recesses between said pintle bearings as seen at l5, Fig. 6 of the drawing to provide a free clearance as at 16 for the cylindrical bearings 10a of the butt 10 of the hinge. This clearance is provided by the cut outs or apertures 12 in the sheet from which the butt 11 is formed, which apertures terminate in the inner wall member at 17 as seen in Fig. 6 of the drawing, and in the outer wall member at 18 to form a stop shoulder.

In forming the butt 1l, and especially in y securing the same tothe pintle 19 of the hinge, which is passed through vthe bearings 14 and 10 the bearings 14 are firmly secured to the pintle by 'applying pressurel and crimplintgxsaid bearings at 1nto aline--I ment wit e free .edge or stop shoulder 18 as seen in Fi y6 of the drawi This operation secure y binck the bearings 14 onto the pintle 19, whereas .the bearings 10Il are free to rotate on said (pintle.

It will also be understoo that the separate sectional portions of the butt 11 may secured together by riveting, welding or in any other desired manner. The shank portion thereof, in the formation of the butt, .1s o'set as seen at 21 at right angles to said shank, and then oiset as seen at 22 into the sides inthe construction of the butt 11 and in the manner of forming the intle bearing portion of said butt from a single sheet of metal, and to ferm of said sheet, a hood portion which encloses the hinge joint throughout the length thereof and provides between the bearings of said butt, within said hood member, recesses to receive the bearingA members of the other butt of the hinge. It will also be understood that the three wall thickness provided where the bearings 14 'are located in the butt 11, produees a strong and durable hinge.

By foldino` the sheet material around a suitable tool 1n the formation of the bearings 14, I provide a knuckle which is insured against opening or spreading when subjected to stress, to a greater degree than knuckles curled at the end of a sheet of metal as is the common practice, it being noted that the stress of the door or swinging member upon the stop shoulder is taken up directly by the hood portion which will prevent the opening or s reading of the pintle bearings or knuc es 14 to a material degree. It will also be understood that with my improved 'method of constructing 4the hinge but-t, all

machining operations are eliminated, and the production costs of the butt reduced to the minimum degree, and yet a strong and durable butt is roduced. p

Y It will a so be understood that myhinge is designed to be used as a single unit or body for hanging and supporting a door in connection with a stationa support or frame without the use of other inge members, and to eliminate the necessity of using a plurality of independent hinges as is the common practice. By means of a hinge off my improved type, considerable time and labor 1s saved in the assemblage and mounting of av door in a frame, and the ro r and. accurate hanging of` the door is acilitated.

In Fig. 8 of the drawing, I have shown a modified method of .forming the butt art 1`1 wherein a similar part 23 is form in substantially the same manner as formn the butt part 11 except that the cylindrica bearing portions 24 are not curled to such va great degree, so that the inner wall 23l of the shank will terminate as 'at 25 to extend onto the bearings 24," and the outer wall 23 at the bearings 24 as well as intermediate said bearings, is spaced from the'pintle in 26 in the formation of the hood 27, the ee edge of which terminates at 28 in the stop shoulder similar to the shoulder 18.

In this construction, the bearings 24 encircle substantially two thirds of the circumference of the pin 26 and extend from the point to the point 29, at which latter ppint, pressure may be applied to bring the arings 24 in alinement with the free edge or shoulders 28 in the operation of rompressing the bearings on the pin 26. With this construction, and by welding the parts 23* and 23" together as indicated at 30 as .well

'as in other places, a strong and durable butt will be provided, and one which will revent opening or spreading of the knuck e to a great degree.

In both forms of constructionlshown, it will be understood that the sheets or overlapping parts of the butt may be. secured together in as many places 'as may be desired by welding, riveting or otherwise, andin the process of forming the butt parts 11 and 23 to produce a strong and durable hinge. If desired,vthe knuckles or bearings 14 may ,be

secured by welding to the adjacentl part of,

the shank of the butt as at the point 14, note Fig. 7 of the drawing to aid in securing the bearings against spreading when subjected to stress, but of course, this welding operation is not absolutely necessary.

It will also be understood that the separate butts of my improved hinge may be constructedV with one or more knuckles cr pintle bearings on\each butt, and the shank portions of the respective butts may be-of any desired shape or contour, depending upon the use of the hinge, it being A'understood that my invention is not limited tothe specific use herein specified. .It will also be apparent that my invention is not limited to iso any particular thickness of metal used in the construction of the-hingey butts or the separate parts of the butts. Further, while I have stated that the bearings 14 and 24 are compressed and secured to the pintle pins of the hinge, it will be understood that thesebearings may be formed on a mandrel or v other core, so that removable pivotv pins may be used in coupling the separate butts of the hinge together.

It will be understood that while I have shown certain details of construction for carrying -my invention into effect, that I am not necessarily limited to these details, and various changes therein and modifications thereof ma be made within the scope of the appende claims without departing from the spirit of my invention or sacrificing its advantages.
